Power banks are by far the smartest portable power solution that helps to charge your dying smart phones and gadgets while travelling or away from a power socket.
If you are someone who likes to go off-the-grid and head on the adventure trails or camping trips for long periods of time then a solar power bank is even a better option that uses sunlight to charge itself which can then be used to charge your phone, tablets and camera cell.
Solar power banks are extremely durable and weather resistant, so you can just attach it to the outside of you backpack at the beginning of your hike and let it charge using solar power throughout the day.
Although, solar power banks can’t charge as quickly as electric power banks and may take a whole day of sunshine to charge your phone fully, but it’s good to know that you have a charging option with you and a half charged battery is better than a dead one.
So, if you decide to opt for a solar power charger, it is best to check a few important factors such as the surface area of the solar panel, size of the battery, compatibility with your devices, durability, safety features, etc.
What is a Solar Power Bank?
A solar power bank is a portable batter that is charged using solar power. All you need to do is put the solar power back in the sun with the solar panel facing the sun light. This type of power banks are especially useful using outdoor trips where there is no availability of electricity sockets. Most quality solar power banks can also be charged by plugging it into a power socket or using USB.
How to Choose a Solar Power Bank?
1. Solar panel
The solar panel is the most important component of the solar power bank that determines the charging efficiency of the power bank. Most solar power banks make use of first-generation crystalline silicon which is great at generating electricity even in low-light conditions.
2. Charging Capacity
Charging capacity of the solar power bank depends on the size and type of battery used in the power bank. Most regular power banks have capacity of 5000 mAh to 18000 mAh. So, if you are carrying several devices with you then it is best to opt for a power bank with larger sized battery. Most solar power banks use either Lithium-polymer or lithium-ion batteries. While lithium polymer batteries are costlier than lithium-ion ones, they are long lasting.
It is important to choose a solar power bank with the right adapters that are compatible with your devices or else you won’t be able to charge your cell phone and tablet using the power bank. It is best to opt for a universal style models that directly connects to your electronic devices using an USB cord.
4. Durability and Portability
Because, solar power banks are used mostly during camping trips and hikes, it is important to choose a power bank that is light weight, compact, durable and weather proof.
